Hearing Conservation Program Flashcards
Hearing Conservation Responsibilities: Commanding officer
establish an effective hearing conservation program withing the command
Hearing Conservation Responsibilities: Commanding officer
establish an effective hearing conservation program within the command
Hearing Conservation Responsibilities: Safety Officer
serves as a liaison to IH Dept and Occ Audio to conduct noise measurement
Safety Officer must maintain records of:
noise hazardous areas
noise hazardous equipment
baseline and subsequent IH surverys
ensure the program is evaluated at least annually
Hearing Conservation Responsibilities: IH officer
maintain and ensure proper calibration of sound level meter
annually, certify audiometric testing booth installed aboard the ships
Hearing Conservation Responsibilities: Division officer
ensures proper noise hazard labeling of spaces and equipment
ensures proper personnel training
sends designated personnel for audiograms
Hearing Conservation Responsibilities: Medical Dept Representative
conducts training for all hands during INDOC and annually thereafter on the HCP
training on HCP should include:
effects of hazardous noise designated noisy areas proper use of PPE necessity for hearing test requirement to wear PPE off duty hearing hazards effects of hearing loss on career longevity communications in high noise environment
Who performs fit test for hearing conservation program
medical dept rep.
who maintains roster of current personnel on HCP
med dept rep
What does the medical dept rep report to the Safety officer on permanent threshold shifts
Name
Rank
Work Center
Time onboard
Hearing Conservation Responsibilities: All Hands
comply with noise hazard labels
undergo annual and any required follow up audiometric testing if enrolled in HCP
program requirements of the HCP:
noise measurement and exposure assessment
labeling of noise hazardous areas with approved labels
noise abatement
personal hearing protective devies
hearing testing and medical surveillance
describe the approved label for noise hazard area
NAVMED 6260/2 (hazardous Noise warning decal, 8” X 10”
NAVMED 6260/2A (hazardous noise label, 2” x 2”
NAVMED 6260/2 hazardous noise warning decal 8 x 10 is posted where
posted outside hatches leading to area
if hatch lead to the weather deck, no decal on outer surface but on the inside of that particular hatch
what is the NAVMED 6260/2A 2x2 label used for
used to label smaller individual pieces of equipment or tools that produce hazardous noise
When is noise abatement accomplished
during ship or equipment design, construction, and testing.
reduction must be explored before implementing other methods of hearing loss prevention
what are areas that must be labeled as a double hearing protection area
equal to 96dBA or great or 165 dBP or greater must be labeled as a noise hazardous area and require the use of double hearing protection
Hearing testing and medical surveillance periodicities:
reference hearing test
monitor hearing test
termination hearing test
reference baseline audiogram form
DD-2215, the baseline at MEPS DOES NOT count
Monitoring audiogram for HCP form number
DD 2216
no protection required for noise levels less than or equal to how many dBA?
84
single hearing protection and placement in HCP noise levels
85 dBA or greater but less that 96 dBA.
double hearing protection and placement in HCP noise levels:
96 dBA
Who takes measurements to measure levels of noise at different sites?
industrial hygienist and or occupational audiologists
Industrial Hygienist or Occupational Audiologist measure noise levels to determine potential hazard and how sound level?
85 dB (continuous or intermittent) or 140 dB peak sound level should be analyzed to determine hazard. Resurvey 30 days after any modifications or changes that could impact
Record of noise measurements shall be kept the measuring activity for how long?
50 years
What is a Significant Threshold Shift (STS)
a change in hearing threshold relative to the current reference audiogram for 10dB or more at 2000, 3000, and 4000 Hz in either ear.
(May be either positive or negative)
STS Identification procedures if the STS is negative
audiogram may be in error. retest the same day. if still showed improved hearing, assume the reference audiogram is in error.
STS identification procedures if the STS is positive
retest after 14 hour noise free environment
supervisor should be notified.
if retest does not indicate STS, return to annual monitoring.
if retest of STS shows positive, and frequencies below 3000 hz involved
screen for med conditions (otoscopy and tympanometry)
record on SF600
if findings through otoscopy and tympanometry are abnormal what must be done
health care evaluation must be obtained and individual followed until cleared medically.
if findings through otoscopy and tympanometry are normal what must be done
perform a second retest
if the second retest does not indicate a STS:
return to annual monitoring
if second retest shows STS:
hearing protection is evaluated
results are forwarded to audiologist/physicians for review and disposition
results usually used to reestablish baseline
within how many days should the supervisors be notified in writing of positive STS?
21 days
OSH office makes entry in what form for a Permanent Threshold Shift?
OPNAV 5102/7 (Log of Navy Injuries and Occupational Illnesses)
within how many days will the worker be notified of a Permanent Threshold Shift?
21 days. signature on dd2216 will suffice as an appropriate notice
what is the purpose of the “noise free audiogram”
exclusion period from noise, “auditory rest”
14 hours is usually sufficient to allow a temporary STS to return to pre exposure levels
Noise Abatement Strategies: Engineering controls
primary means of protection
acoustical enclosures
engineering designs to eliminate or reduce noise levels
Noise Abatement Strategies: administrative controls
secondary means.
limiting times of exposure
Noise Abatement Strategies: Substitution
substitution of less noise operations
types of personal hearing protective devices
ear plugs disposable single flange triple flange straightaway muffs circumaural muffs
training requirements for personnel enrolled in the NHCP:
trained PRIOR to working in hazardous areas
training shall be conducted on an annual basis
